1 Claim. (Cl. 248-48) This invention relates to mounts for television orradio antennas, and more particularly, has reference to an improvedmount that summarized briefly, comprises a vertically extending,upwardly opening pipe socket adapted to receive an antenna mast, aplurality of downwardly divergent legs detachably secured to said pipesocket, brace means extending between the legs and the lower end of thepipe socket, and adjustable feet or clips carried by the lower,divergent ends of the legs for adapting the mount for installation onvariously pitched roofs.

One object of importance is to provide an antenna mount which willsimplify to a marked degree the installation of an antenna theconstruction being such as to permit a single man to easily and quicklyinstall an antenna in far less time than is regularly required followingconventional installation practices.

Another object of importance is to provide an antenna mount as statedwhich not only will reduce the cost'of installation by the abovementioned reduction in labor cost, but which is at the same time itselfcomposed of easily assembled, simply designed components, thus to reducethe basic cost of manufacture of the device.

Still another object is to so form the antenna as to simplifymanufacturing costs and installation procedures without sacrificingruggedness and durability of the mount.

Another important object is to provide an antenna mount which willeliminate the use of guy wires, the mount being so designed as tosupport a mast of substantial height without danger of said mast,toppling or bending under heavy winds.

Yet another object is to form the antenna mount with means at the lowerend thereof which will permit the adjustment of the same to any pitch ofroof, and which will, in fact, permit the mount to be erected on flatroofs as well as in position over the ridge peak of variously pitchedroofs.

Still another object is to provide an antenna mount which will, whenerected, have a more attractive appearance than conventional mounts nowin use.

A further object is to provide an antenna mount of knockdowncharacteristics, which can be shipped in a relatively small carton, andwhich can be swiftly assembled when it is to be installed.

Other objects will appear from the following description, the claimappended thereto, and from the annexed drawing, in which like referencecharacters designate like parts throughout the several views, andwherein:

Figure 1 is a perspective view of an antenna mount formed in accordancewith the present invention, as it appears when in use;

Figure 2 is an enlarged top plan view of the mount per se;

Figure 3 is a vertical sectional view on line 33 of Figure 2;

Figure 4 is a vertical sectional view on line 44 of Figure 2;

ice

Figure 5 is a transverse sectional view on line 5-5 of Figure 4; and

Figure 6 is a perspective view of the socket assembly of the mount.

Referring to the drawings in detail, the reference numeral 10 generallydesignates a conventional television antenna, 12 the antenna mountconstituting the present invention, and 14 a pitched roof on which theantenna is to be erected.

The mount 12 constituting the present invention includes a relativelyelongated, vertically extending, upwardly opening mast socket 16 closedat its lower end by a rectangular base plate 18 having a centrallydisposed drain opening 20 and a series of corner openings 22. Spacedlongitudinally of the socket 16 are set screws 24 threadable inwardlyagainst the mast to firmly engage -the same in the socket, the setscrews being provided with lock nuts 26 which are turned home againstscrew-receiving bosses formed upon the socket after the set screws havebeen clampably engaged against the mast.

Intermediate the opposite ends of the socket 16, but closer to the upperend than to the lower end, the diametrically opposed, angularly bentsmall ends of flat, downwardly divergent, approximately triangular legattachment plates 30 are welded or otherwise fixedly secured. Two pairsof elongated legs 32 of L-shaped cross section are provided, the legs ofeach pair diverging in a downward direction and being connected by asingle bolt 34 to the opposite sides of the associated attachment plate30. As will be noted from Figures 1 and 2, the downwardly divergent sideedges of the attachment plates 30 are engaged against the associatedlegs 32. The screws 34 are located at the lower corners of theattachment plates 30, and thus when the device is being assembled, thelegs 32 may initially be swung together in par allel relation tofacilitate carrying of the assembly, to the roof after which the legs 32are swung outwardly to the positions thereof illustrated in the drawing,into engagement with the side edges of the associated attachment plates30. This is of course at the users option, and one can instead assemblethe device fully either on the ground or on the roof, wherever is moreconvenient.

Welded or otherwise fixedly securedto the respective legs 32,intermediate the opposite ends thereof are brace rods 36 extendingradially and inwardly of the mount toward the brace plate 18, and havingat their inner ends, depending, short extensions 38 engaged in thecorner openings of the base plate. The rods 36 are inclined slightlyfrom the horizontal as shown in Figure 4, downwardly in the direction ofthe base plate from their fixed connections to the legs 32.

Integrally formed upon the lower ends of the several legs 32 are short,depending, vertical extensions 40, connected to short feet 42 ofright-angled cross section by I means of a single bolt 44. The bolt 44provides a pivot about which the feet 42 can turn, thus to adjust thefeet to any pitch of roof.

It will be apparent that the device is of such design as to permit it tobe knocked down completely, preliminary to shipment and sale. Thisreduces measurably the cost of transportation, and at such time as themount is to be placed in use, the several legs 32 can be swiftlyassembled with the pipe socket, merely by connection of the bolts 34 tothe attachment plates 30 and engagement of extensions 38 with base plate18. When the mount is erected, of course, screws are extended throughthe base portions of the feet 42, with said feet adjusting themselvesautomatically to the pitch of the roof by reason of their being disposedtransversely of the peak of the roof. The completely erected mountresists pressures effectively, so that the mast is firmly supported insuch a position as to minimize to the fullest extent possible the dangerof bending the mast or toppling thereof. This is achieved without theuse of guy wires, since a substantial portion of the mast is engaged inthe socket, with no loss of desired elevation of the antenna due to theelevation of the socket itself a substantial distance above the ridgepeak.

It is believed apparent that the invention is not necessarily confinedto the specific use or uses thereof described above, since it may beutilized for any purpose to which it may be suited. Nor is the inventionto be necessarily limited to the specific construction illustrated anddescribed, since such construction is only intended to be illustrativeof the principles, it being considered that the invention comprehendsany minor change in construction that may be permitted within the scopeof the appended claim.

What is claimed is:

An antenna mount comprising: an elongated, tubular, vertically extendingmast socket open at its upper end; a base plate closing the lower end ofthe socket, said plate including a marginal portion projecting laterallyoutwardly from the socket; means on the socket for clampably engaging anantenna therein; a pair of identical but opposite leg attachment platesfixed to the socket intermediate the ends of the socket, each platehaving upwar'dly convergent side edges symmetrically arranged in respectto the length of the socket at opposite sides thereof, said plates lyingin downwardly divergent planes symmetrically arranged in respect to thelength of the socket at opposite sides thereof, corresponding side edgesof the plates being in registration with each other transversely of thesocket; pairs of legs, one for each plate, each pair being coplanar withits associated plate and the legs of each pair being respectively inlongitudinal alignment with the respective side edges of theirassociated plate, the legs of each pair being pivotally connectedintermediate their ends to their associated plate for swinging movementabout axes normal to the plane of their associated plate and disposedsymmetrically in respect to the socket at opposite sides thereof, eachleg including a portion projecting across the plane of its associatedplate for engaging a side edge of the plate on swinging movement of theleg in one direction to limit swinging of the legs in said direction;elongated brace rods rigid at one end with the respective legs andprojecting radially of the socket from the legs, said marginal portionof the base plate having openings angularly spaced about the socket, therods having extensions at their other ends removably engaged in saidopenings on swinging of the legs in said direction to positions in whichsaid portions of the legs are in engagement with the side edges of theirassociated plates; and supportingsurface engaging feet on the severallegs, formed as short bars pivoted on the lower ends of the legs forswinging movement about axes parallel to the pivot axes of the legs.
